As a child, Gay McDougall was banned from many public places in Atlanta. When she finished high school, she was chosen to be the first black student to integrate Agnes Scott College in Decatur, Georgia. Looking back on the experiences of her early years, she has said: "We believed then that our situation was uniquely tragic... We often looked to the international community with the hope that somehow the world beyond this country operated on different rules…We were both right and wrong."
McDougall is currently a Distinguished Scholar-in-Residence at the Leitner Center on International Law and Justice, Fordham University Law School In 1998, she was first elected to serve as an independent expert on the United Nations treaty body that oversees the International Convention on the Elimination of All Forms of Racial Discrimination. She was the first American to be elected to the body of 18 international experts who oversee compliance by governments worldwide with the obligations established under the treaty. She served a four-year term, from 1998 to 2001. She was elected to another four-year term on the CERD Committee in June 2015, and currently serves on the Committee for a term that began on January 20, 2016, and is scheduled to end on January 19, 2020. She is currently a Vice-chairperson of the Committee. At its 1996 session, the United Nations Commission on Human Rights elected her to serve a four-year term as a member of the U.N. Sub-Commission on Prevention of Discrimination and Protection of Minorities of the Human Rights commission. She also served as Special Rapporteur on the issue of systematic rape, sexual slavery, and slavery-like practices in armed conflict, in which capacity she presented a study to the United Nations Sub-Commission on Human Rights that called for international legal standards for prosecuting acts of systematic rape and sexual slavery committed during armed conflict. As Special Rapporteur she also toured Sierra Leone with the U.N. High Commissioner for Human Rights to assess the devastating impact the civil war had on civilian populations. Prior to joining Global Rights, McDougall served as one of five international members of South Africa's 16-member Independent Electoral Commission which successfully organized and administered that country's first non-racial elections. During southern Africa's apartheid era, she was director of the Southern African Project of the Lawyers' Committee for Civil Rights Under Law from 1980 until early 1994 and gave direct assistance to the defense of thousands of political prisoners in South Africa and Namibia by financing the defense and collaborating with attorneys. In 1989, McDougall founded the Commission on Independence for Namibia, a bipartisan group of 31 distinguished Americans who monitored in detail the year-long process to independence mandated by the U.N. The Commission intervened to force modifications in critical legislation, such as the voter registration and election laws, which as drafted, threatened the fairness of the election process.
